What is a non-optical microscope that magnifies up to 250000?
A transmission electron microscope could do this magnification.
What is the lens that is closest to the eye in a light microscope?
On a microscope with the usual 3-lens turret it is usual to use the objective lens with the lowest magnification to first examine your specimen. This gives a wider overall view of the subject, and will allow you to choose the particular detail that best suits your study. You may then move on to a higher magnification, if necessary, to study finer detail. If you started with the highest magnification, your fine focus will be uncertain, and you risk the front of the objective lens coming into contact with the sample slide. This could damage your specimen, and may damage the front of the lens.
The ocular objectives are found at the top and bottom of what part of a microscope?
AnswerWell, the ocular lens is what you look into to see the specimen and the the objective lens is the closest frame to the specimen so they would be connected to the body tube.
Who first used a microscope?
The first compound microscope was made circa 1590 in The Netherlands. Hans Lippershey, Sacharias Jansen, and Hans Jenssen, all eyeglass makers, have each been given credit for the invention, using two separated lenses to greatly increase magnification. About 1670, Anton van Leeuwenhoek dramatically increased the magnifying power of the simple microscope by creating small spheres of high-quality glass, from which powerful lenses could be made.
The best reason for using a scanning electron microscope?
advantages of SEM 1- large depth of field 2- much higher resolution 3- high magnification 4- we could use it for bulk material
What is the magnifying power of the eyepiece used if a cell magnified 200 times under HPO?
Impossible to answer ! 200x magnification could be created by an eyepiece with 4x and an objective lens of 50x magnification - but that's just ONE example !
What is the maximum power of magnification of a microscope?
Actual magnification of light microscopes could reach up 1000x magnification depending on the type of light microscope. Light microscopes could be divided into brightfield microscope and phase-contrast microscope for viewing stained specimen and unstained specimen respectively. Magnification of electron microscope on the other hand could go up to 1000000x. The actual magnification as well depends on types of electron microscope which includes transmission-electron microscope and scanning-electron microscope where both of them are used in viewing internal cell structures and cell surface structures respectively.

A transmission electron microscope could do this magnification.
Would a microscope that enlarges an object 400 times have a resolution of 400?
No. It would have a magnification of 400. The resolution is not directly related to the magnification. It could be higher or lower.
What type of microscope would be best to use if you wanted to look at the parts inside of a cell?
you could use any regular microscope that has magnification up to 400 but the best type of microscope to use would be an electron microscope if you could afford one

Why could viruses not be seen before 1938?
Viruses could not be seen because the resolution and magnification was not good enough until 1938 when Ernst Ruska developed the electron microscope.
Who invented the modern microscope?
Anthony van Leeuwenhoek is credited with developing the modern microscope, but it could not be said that he invented the first microscope. He improved upon previous inventions by increasing magnification by up to 270 times the size of the sample being studied, using a single lens. The invention of the precursors to the modern microscope is credited to Dutch eyeglass makers Hans Lippershey and Zacharias Janssen, who each - independently - had input into using glass and lenses to increase magnification.
What is the strongest magnification power?
depends which microscope ur using..... the strongest (not NASA's) is about 1,000x The definition of magnification power is given by the relationship: Magnification = 250 mm / f Thus, a 25-mm focal-length positive lens would be a 10x magnifier.
What types of objects can be studied with a light microscopes. what types can be studied with an electron microscopes?
Light microscopes are used to study living organism and to watch and analyze their structures. Electron microscopes use a dead specimen and are able to observe structures in great detail and with much much higher magnification. +++The electron microscope has a far higher definition and magnification than an optical microscope could achieve, but as you say you could not use it to study a living organism.
What is a jewelers eyepiece called?
A loupe is a small magnifying lens that could be described as a jeweler's eyepiece.
